That's a little tight on the right side, but the dirt strip shows where cars don't drive, a bike could fit there, but not much room for error from the drivers. If it's long stretches of sidewalk like that with no/rare driveways/pedestrians, I'd go ahead and ride on the sidewalk. And on the way home, the other side of the street looks like a nice trail, as long as you have suitable tires (like I do!)
